Mustang Jam Nut TFOCA-II® Optical Media Converters

Mustang Optical Media Converter

Moog Protokraft Mustang series dual fiber optic Ethernet media converters consist of optoelectronic transmitter and receiver functions integrated along with the 10/100Base-TX to 100Base-FX or 1000Base-T Ethernet electrical to 1000Base-SX Ethernet optical media conversion circuitry into an environmentally sealed unit with a Jam Nut TFOCA-II® optical connector interface.

The optical transmitters are high performance 1310 nm FP Lasers, LEDs or 850 nm VCSELs. The optical receivers consist of GaAs or InGaAs PIN and preamplifier assemblies and limiting post-amplifiers. The optical interface to the Mustang series optical media converters is a TFOCA-II® connector enabling interconnection to preterminated TFOCA-II® based optical fiber cable assemblies. The electrical interface to the Mustang series optical media converters is either a MIL-DTL-38999 connector for external 28 VDC connections or a Samtec® SMT connection for internal 3.3 VDC applications. USB powered configurations are also available. These options enable robust and simple interconnection to Ethernet switches, routers or NICs.
